"A strong Santa Ana Wind event is expected to develop Monday and last through at least Tuesday," the National Weather Service said.

After a weekend of reprieve allowing fire teams to continue making progress battling the deadly infernos burning in Los Angeles County, Southern California now faces another round of fire-fueling Santa Ana Winds Monday.

Southern California is facing fierce fires fueled by the Santa Ana winds, which threaten homes and put firefighters to the test.

The Santa Ana winds are dry, powerful winds that blow down the mountains toward the Southern California coast. The region sees about 10 Santa Ana wind events a year on average, typically occurring from fall into January. When conditions are dry, as they are right now, these winds can become a severe fire hazard.

Parts of Los Angeles, Orange, Riverside and San Bernardino counties all will be under a red flag warning beginning on Monday morning, the NWS said. The strongest Santa Anas are expected Tuesday morning.

The National Weather Service has issued another rare Particularly Dangerous Situation warning in anticipation of Monday's Santa Ana wind event.

As winds across the Southern California area are calmer than their peak and firefighters are making progress, the threat to the fire-weary region remains with Santa Ana winds expected to continue in the coming days.

Gusts of up to 70 mph are possible along the coast and valleys, and in the mountains, up to 100 mph, the National Weather Service said. Parts of L.A. County, and most of Ventura County, are at highest risk.
